Embodiment 1

[0047] Biological Example 1: Field efficacy of chlorfluazuron, indoxacarb and their compound against Plutella xylostella.

[0048] The field experiment was arranged in Yugan County, Jiangxi Province. The test chemicals were provided by Jiangxi Zhengbang Biochemical Co., Ltd. The pesticides were applied at the 2nd instar larvae of Plutella xylostella xylostella, and each drug treatment was repeated 3 times. Investigate the base number of insect population before spraying and the number of surviving insect populations 5 and 7 days after spraying to calculate the average control effect. The test results are shown below.

Embodiment 2

[0053] Biological Example 2: Field efficacy of hexazuron, tebufenozide and their compound in control of beet armyworm.

[0054] This experiment was arranged in Jinxian County, Jiangxi Province. The test agent was provided by Jiangxi Zhengbang Biochemical Co., Ltd., and the drug was applied at the 2nd instar larvae of beet armyworm. Each agent treatment was repeated 3 times. Investigate the base number of insect population before spraying and the number of surviving insect populations 5 and 7 days after spraying to calculate the average control effect. The test results are shown below.

[0056]

[0057] The test results show that the combination of chlorfluazuron and tebufenozide can effectively prevent the occurrence of beet armyworm, and the control effect is significantly better than that of the control single agent (chlorfluazuron, tebufenozide), and the drug cost i...

Embodiment 3

[0058] Biological Example 3: Field efficacy of hexazuron, acetamiprid and their compound in controlling cucumber thrips.

[0059] This experiment was arranged in Nanchang City, Jiangxi Province. The test chemicals were provided by Jiangxi Zhengbang Biochemical Co., Ltd., and the drugs were applied during the outbreak period of thrips adults. Each drug treatment was repeated 3 times. Investigate the base number of insect populations before treatment and the number of surviving insect populations 1 and 4 days after treatment to calculate the average control effect. The test results are shown below.

[0060] Table 3 Efficacy test of hexazuron, acetamiprid and their compound in controlling cucumber thrips.

[0061]

[0062] The test results show that the combination of chlorfluazuron and acetamiprid can effectively prevent the large-scale occurrence of cucumber thrips, and the control effect is significantly better than that of the control single agent (chlorfluazuron, acetam...

Abstract

The invention provides a pesticide suspending agent containing chlorfluazuron and butene-fipronil and a preparation method of the pesticide suspending agent. The pesticide suspending agent comprises an active component A which is chlorfluazuron and an active component B which is butene-fipronil. A pesticide effect of the pesticide suspending agent provided by the invention is superior to that of conventional powder and emulsion oil, and meanwhile, a lot of harmful solvents used in the emulsion oil are avoided. The pesticide suspending agent is less in average grain size, high in suspensibility, stable in performance and extremely small in water bleeding amount when being preserved at normal temperature within two years. The pesticide effect of the compound pesticide suspending agent is remarkably superior to that of the single component chlorfluazuron or butene-fipronil.

Description

[0001] This case is a divisional application of Patent Application No.: 2011103979621, Invention Name: Pesticide Suspension Containing Chlorfluazuron and Its Preparation Method. technical field [0002] The invention relates to a pesticide preparation and a preparation method thereof, in particular to a suspension of a pesticide composition containing chlorfluazuron and a preparation method thereof. Background technique [0003] Chlorfluazuron, also known as difenuron, impatabo, and flufenuron, is a benzoylurea insecticide developed by Ishihara, Japan. The mechanism of action of chlorfluazuron is to inhibit the synthesis of chitin, hinder the normal peeling of insects, cause egg hatching, larval peeling and pupae development deformity, adult eclosion is hindered, it has stomach poisoning and contact killing effects, high efficacy, and slow action speed. It can effectively control pests such as Lepidoptera, Orthoptera, Coleoptera, Hymenoptera, Diptera, etc. in vegetables, cot...
